IMPROVEMENT IN FANNlNG-MILLS.

The Schedule referred to in these Letters Patent and making part of thesame.

I', Hannrson Oeeonn, of Richmond, in the county of Wayne and State ofIndiana, 'have invented certain' Improvements in Fanning-Mills, Grainand Seed-Separators, of which the following is a specification. I v l Myinvention consists in new and improved devices for cleaning springwheat, winter wheat, and? other kinds of grain and seeds, in a mannerhereinafter described 'Figure 1 isJa perspective view of a machineembodying my invention.

Figure? is a detached sectional view of the same.

- Figure 3 is a top view of the lower end of the lower shoe.

. Figure 4 is a back end View of a portion of the upper shoe, and thehorizontal pins or arms on which the inner end of theupper shoe rests.

Figure 5 represents the rock-shaft and its connections. I

A A is the frame of my machine, which should be substantially made toresist the shaking motion of the machine.

B is the lower shoe, in which the two long screens are held; g

O is the fan-case;

D is the tan-drum;

E is the crank; and

b, the handle to the same.

1! is an opening in the post A, made to receive the driving-wheel.

G', pinion on fan-shaft for rotating the same.

H, fan-door, for opening and closing the wind-hole in the drum.

I, shaker-arm for lowershoe.

K, rocker-arm. 1

L,holes inrocker-arm to adjust the degree of shake.

M, suspending-rod. Y

N, pivot onsuspending-rod.

O, pivot-plate.

P is the upper shoe for holding the short screens.

Risa board in the bottom of the long shoe, inclined backward so as torun the screenings away from the wheat as it falls from the shoe.

S is the bottom board to the lower vshoe, over which the chess, cockel,small oats, and other impurities pass before falling from the shoe.

T, bottom of market-wheat spout.

U, opening for the small grains of wheat to pass through.

V, bottomof seed or large-wheat spout.

W, outlet' for the same.

X, open space through which the screenings fall.

a isthe master-wheel for running the machinery.

c, suspending-strap for lower shoe.

d,- fan-case opening for the admission of air.

. e, suspending-strap in rear of upper shoe.

9 is a nest of screens, used for taking oats from wheat, which can beset at any angle and held in position by a rod passing through'the shoe,on one end of which a screw is cutto receive a thumb-screw nut; Thesescreens may be used for many other purposes, also.

h h are grooves in the upper and lower shoes to re ceive thevariousscreens for the various kinds of cleaning.

Zis a sliding board in the bottom of the hopper, for opening and closingthe same.

m is a knocker, one end of which strikes a pin, a, passing through thebottom of the shoe, the upper end of which pin comes in contact with ablock on the under side of the cross-piece in the lower screen, whilethe upper side of the lower long screen comes in contact with a blockfastened on the lower side of the upper long screen, which brings theblock on the upper "screen against the lower screen, so that the knockerjars the two long screens equally and simultaneously.

The doors to the wind-holes ,are'made so that they are .held by a smallwire, a, in any desired position, to cover all or any part ofthe holesin the ends of the drum.

The machine is capable of a great number of variations, both in thecombination of the screens and the various degrees of shake; the upperscreens and shoe vibrate sidewise by the usual bell-crank and rods,while the long or lower screens operate endwise, so-that the upper shoemay be made to operate entirely independently of the lower, and also thelower one independently of the upper; 1

The blast being. regulated, and the shake of the upper and lower shoesmade to conform to the requirements of the case, motion is communicatedby the master-wheel by thehandle and crank, and from the master-wheel tothe pinion G, and by it to the fan-shaft, and also from the pinion by arod, I, to the rocking-shaft, the end of which is seen at w, fig. 1.

The vertical motion of the arm K communicates a horizontal shake to thelong shoe and screens; ,at' the same time the crank-pin (t communicatesmotion to the bell-crank a, and thence by the short rode to the uppershoe, said upper shoe being especially adapted to cleaning oatsfrom-spring wheat and other difiicult kinds of cleaning. 1 7

At the same time the two shoes are put in operation, the rod m, attachedat (0 receives an end motion,

which in turn communicates a vertical motion to the knocker 1, wherebyit is made to strike the pin 0,

and fed onto the nest of screens by drawing the bottom board out to anydesired position. The wheat falls onto the nest of screens and the lightchaffy particles are blown over behind the machine, while a porcats willbe carried over in like manner until the process is carried to itssuccessful termination so far as the nest of screens can accomplish it.The wheat and short oats and other impurities fall from the nest' ofscreens toward the long screens, when the blast of air from the fan willblow over a portion of the re-' maining impurities, when it is subjectedto a final sifting and jarring motion bywhich the small particles passthrough the screen 0, while the large grain passes down over the. screen-0 and falls through the opening W into any convenient vessel.

The small wheat, and also other impurities, pass onto screen d, wherethe small grains of wheat are retained, as d is a finer mesh thanc, andparticles smaller than the wheat fall through the lower screen onto thebottom board, and fall to the floor through an opening, X, in the bottomof the shoe. Meanwhile, the screend retains the small grains of wheatfrom which they fall from the shoe through the hole U in theshoe-bottom.

" combination with shoe B, when said parts are constructed and arrangedfor operation substantially as described. I

2. The adjustable knocker t, rod n, pin 0, and blocks h 7:,iucombination with screens 0 and d, in shoe B, as and 'for the purposedescribed.

3. The shoe I, when supported at its forward end on pins 7), and at itsrear'end by suspension-strap e, in combination with bell-crank x, androds Y and z, as and for the purpose described and set forth.

4. In combination with the shoes B and I, and their respective series ofscrcens,'the troughs T and V, when provided with the openings \V and U,arranged as shown and for the purpose described. I

5, The combined fanning-mill and grain-separator described, consistingof the. several parts and mech anisms hereinbefore specified,constructed, combined,

and arranged to operate substantially in the manner and for the purposedescribed and set forth.
